CA 2029234

A crusher having a pair of spaced rollers mounted on shafts. One of the rollers is moveable with respect to the other roller and the movement is by a pair of screw jacks in conjunction with a pair of toggle assemblies. The moveable roller is supported by moveable bearing housings at ends of its shaft. The toggle assemblies apply a force to the moveable bearing housings to slide each moveable bearing housing along a bearing support and a track located on each side of the crusher. Each roller comprises a pair of roll hubs mounted on the shaft, an expansion ring and a roll shell. Roll wedges are located between the expansion ring and the roll hubs and the roll wedges are drawn together by bolts to provide a radially outward force on the expansion ring which holds the roll shell in place.
